A CPAP delivers consistent air pressure to the patient
Sleep studies are the most efficient way to diagnose sleep apnea and other sleep disorders. There are two different classes of PAP machines, and these are Bi-level CPAPs or VPAPS and CPAPs. Your sleep doctor or supplier can help you decide which device would be the most efficient and easy for you.
Most continuous positive airway pressure or CAP devices are just a little bigger than a shoe box and use air pressure to keep your airways open while you sleep. There are also dental devices that help, or you can have surgery to keep blocked airway passages open. However, only a CPAP machine can keep the airway in the lower part of your airway tract open. A CPAP machine delivers one consistent air pressure that does not change with inhalation or exhalation.
